1 Claim.

the flame is spread in a manner resulting in a smooth flowing flame freeof flicker.

Another object of the invention is to provide a device of this kindwhich can be readily and conveniently applied to or removed fromoperative position with respect to the burner proper.

The invention consists in .the details of construction and in thecombination and arrangement of the several parts of my improvedattachment for an oil burner whereby certain important advantages areattained and the device rendered simpler, lessexpensive and otherwisemore convenient and advantageous for use, as will be hereinafter morefully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanying drawing,wherein:

Figure 1 is a vertical sectional view illustrating an attachmentconstructed in accordance with an embodiment of my invention and inapplied position;

Figure 2 is a view in top plan of the attachment as herein disclosedwith the top or spreader plate removed;

Figure 3 is a fragmentary detailed sectional view taken substantially onthe line 3-3 of Figure 1.

As disclosed in the accompanying drawing, C denotes a casing of anydesired dimensions and configuration and which is open at its lower endand which has said lower end portion intersected by the cross members 2.Resting upon these cross members 2 at the central part of the casing Cis a burner B of a well type. This burner B is preferably of cast ironand is provided in its side wall with the air inlet openings l and inits upper portion with the vertically spaced and inwardly disposedcontinuous flanges 3 defining the central openings 4. The top of theburner B, which is of a pot type, is also provided at its top with anoutstanding surrounding flange 5 which has close contact with the sleevemember M surrounding the. applied burner B and resting upon and suitablysecured, as at 6, to the members 2. The bottom of this sleeve member Mis open while the upper end I is closed.

The casing C is provided with suitable supporting legs 8 for maintainingthe casing raised above the surface upon which it is supported so thatair may readily pass up through the lower open end of the casing Caround the sleeve member M and also up between the member M and theburner B for flow into the burner B through the openings I. The lowerportion of the burner B receives the oil which is delivered theretothrough the pipe line 9 leading from a' suitable source of supply, andthe member M at a point closely adjacent to the top I thereof has incommunication therewith a flue F for carrymg off the products ofcombustion and, of course, creating the desired draft.

The foregoing features of the stove as described form no part of mypresent invention as the same are in accordance with the type of oilheater now already known.

As herein embodied, my improved attachment comprises an elongated hollowmember I0 preferably circular in cross section, and which has its lowerend ll closed with the opposite end open. The Wall of this member [0 isof material thickness and said wall adjacent to its upper or open end isprovided therearound with a plurality of outstanding loop members l2. Asillustrated in the accompanying drawing, these members l2 are three innumber and equidistantly spaced circumferentially around the member I0.The member ID is adapted to be supported substantially axially of theburner B by the props Hi, there being one of such props M for each ofthe loop or eye members l2; The props i4 each comprises, in the presentembodiment of my invention, an elongated bar provided at one end with anangularly related arm Hi. This arm I5 is short and straight and isinsertible from below through one of the eye members I2 as particularlyillustrated in Figures '1 and 2. arm 15 is snugly received within an eyemember l2 with said straight arm H: in contact with the adjacent portionof the member I0 when the prop I4 is engaged with the desired supportingsurface for the attachment which, in the present instance, is the flange3 of the burner.

The degree of angle of the arms l5 with respect to the props l4together, of course, with the length of such props determines the extentthe upperend of the member I0 will be above the burner and, as isillustrated in Figure 1, it is to be The cate sections eachsemi-circular in form and the meeting edge portions of said portions atthe longitudinal center thereof are provided with the extended lugs [8which, as is illustrated in Figure 1, are snugly received within theupper end portion of the member ID whereby the plate [6 is maintained indesired position upon said member 10.

The side wall of the member M is provided with a suitably positionedopening [9 normally closed by a plate or the like. Aligned with thisopening 1.9 is an opening 2| in the side wall of the casing C. Thisopening 2| is normally closed by a plate 22. The openings [9 and 2| areof such diameters to readily permit the mounting or placing of myimproved attachment upon the burner B as well as the removal of theattachment. 1

The flow of the air into the burner B through the openings l and outthrough the openings .4

will draw ofi therewith vapor from the liquid fuel in the bottom of theburner B with the result that the combustion will be within the upperportion of the burner B with the flame passing outwardly through theupper opening 4 and spread by the plate l6 which will result in a smoothflowing flame free of flicker and such flame willbe circular in form asit passes upwardly beyond the assembled and operated, and it will alsobe obvious that my invention is susceptible of some change andmodification without departing from the principles and spirit thereofand for this reason I do not wish to be understood as limiting myself tothe precise arrangement and formation of the several parts herein shownin carrying out my invention in practice except as hereinafter claimed.

I claim: n

An attachment for comprising an elongated hollow member closed at oneend, outstanding loops at the opposite end portion of the elongatedmember and spaced circumferentially therearound, props provided withangularly related arms at the ends thereof for insertion from belowthrough the loops, said" props providing means for supporting saidmember upon the burner with said elongated member extending downwardlyand substantially axially of the burner, a substantially flat spreaderplate provided at its axial center with a part fitting within the openendiportion of the elongated member whereby the spreader plate issupported by said elongated member above the burner, said spreader plateand elongated member being of a material to become red hot from theflame of the burner, a'marginal portion ofthe spreader plate beingupwardly and outwardly disposed.
